6.3.3 Valve DeadZone Test
1. Follow the steps, 6.1.1 to 6.1.3 (level booms, working RPM,
etc.), before proceeding.
2. Ensure the UC4+ control panel is in MANUAL mode, at the
Normal Operating Screen.
3. Navigate to the "More ?" menu prompt in the SETUP menu
Toggle the "AUTO (YES)" switch to confirm.
4. Navigate to the boom section you wish to setup, for example,
"Right ?" to adjust the right up and/or the right down
settings. Toggle the "AUTO (YES)" switch to confirm.
5. Toggle the "SETUP (NO)" switch to access the next menu
prompt, in this case the right up DeadZone ("-DZÇ").
6. While viewing the DeadZone ("DZ") menu prompt, perform one
of the two tests: AUTO DeadZone Test or Manual DeadZone
Test.
NOTE: You do not need to run both the AUTO and Manual
tests. The tests are entirely independent.
a) Auto DeadZone Test
• Toggle and hold the "AUTO (YES)" switch.
• When the "Done" message is displayed, release the
"AUTO (YES)" switch to view the new setting.
b) Manual DeadZone Test
• Toggle and hold the "MANUAL" switch.
• The valve will turn on at the indicated setting for exactly
one-second. The LCD screen will show the actual change in
height.
• The change in height reading is live as long as you hold the
"MANUAL" switch. Wait until the height reading has
settled to a stable value and record this reading.
• Average your three readings. The acceptable average
change in height should be from 13 to 38 mm (0.5 to 1.5
inches) (ideal would be 25 mm (1 inch) exactly).
• If the average is less, increase the DZ setting with the " +/- "
switch. If the average is more, decrease the DZ setting with
the " +/- " switch.
• Repeat the Manual Dead Zone Test until the average falls
into the acceptable range.
